The developer 1X2gaming thematizes police procedures, steampunk, and detective fiction in its investigative July 2019 video slot Sherlock’s Casebook, which is adapted from the protagonist Sherlock Holmes—operating from 221B Baker Street—fictionalized in Arthur Conan Doyle’s literary works.

Relating with I am the Law (1X2gaming; May 2019), Sherlock’s Casebook’s regularly pays from X5 to X1000 if—out of its thirteen symbols—ten symbols (J, Q, K, A, cap, tobacco pipe, violin, handgun, magnifying glass, and signpost) form a three/four/five-of-a-kind; other features: two substitutes (locked and reel-tall), nine total bets, and free games.

Sherlock’s Casebook Games Characteristics

The Sherlock’s Casebook’s unpartitioned and translucent 5X3 grid—its frame consists of a bronze piping system—is set between guard rails and an icy steampunk engine overlooking tiered and domed white towers in the wintry background amid a railroad’s viaduct.

The Sherlock’s Casebook total bets: $0.25 (minimum), $0.50, $1.00, $1.50, $2.00, $2.50, $3.00, $4.00 and $5.00 (maximum)—up to $100.00 bet in other versions.

Sherlock’s Casebook has three special and ten ordinary symbols. Special symbols: the regular substituting wild is a reel-tall feathered top hat-wearing, brown-haired, and lean Sherlock Holmes; the free games’ activator is a ginger-haired blue-dressed queen; and the free games-only substitute is a sticking fedora-wearing, ginger-haired, mustached and heavy-set “wild” Dr Watson.

Ordinary symbols: fancy brown J, blue Q, purple K, and cyan A; checked brown deerstalker cap; tobacco pipe; brown violin; handgun; magnifying glass; and white “221B Baker St” signpost.
